I don't mean this to sound like a "sweet lemon" rational, but I just upgraded to a XFX HD 5770 from an overclocked PNY 9800 GT 1 GB. Using Unigine Heaven v1.0 benchmark, I tested both cards in DX10. The 5770 scored 1538 vs 990 of the 9800 GT. if you have the room for the larger card 10.5" and your power supply is minimum 450 Watt. I highly recommend it. I was getting tired of Nvidia's heat production and higher wattage requirement. This is the first ATI card I have bought since a 128 Rage pro. I bought the 'egg shaped' newer design card, it has larger radial cooler, with a bigger thus quieter fan. It idles at 41c. I gave the DX11 benchmark a whirl and I must say tessellation really adds depth. I think that the HD 5770 will keep you happy through the adoption of DX11 in games. I haven't done any ray trace or mental ray renders yet, but based on the benchmarks I am sure it is an improvement.
